fication.

My invention relates to looms, and more particularly to areversingmotion for the take-up adapted to be used in connection withthe well-known Knowles head-motion shown and described in ReissueLetters Patent No. 7,784 and with the system of reversegears shown anddescribed in United States Letters Patent No. 398,328.

The object of my invention is to provide a mechanism adapted to becombined with and used in connection with said Knowles headmotion andsaid reverse-gear mechanism and with the take-up motion to reverse ormove backward the take-up roll at the same time that thepattern-cylinders are reversed or moved back by said reverse-gearmechanism.

My invention consists in certain novel features of construction of myimprovements,

as will be hereinafter fully described.

I have only shown in the drawings detached parts of the said Knowleshead-motion and of said reverse-gear mechanism and of the driving-shaftof the take-up roll and my improvements combined therewith sufficient toenable those skilled in the art to understand the construction andoperation thereof.

Referring to the drawings, Figure 1 shows a detached part of saidKnowles head-motion and said reverse-gear mechanism looking in thedirection of arrow a, Fig. 3, and the upright driving-shaft and theshaft to the takeup roll and my improvements combined therewith. Fig. 2shows a rear view of the gears and other parts shown at the lower partin Fig. 1 looking in the direction of arrow I), samefigure. Fig. 3 is afront end view of the parts shown in the upper part of FigIjl looking inthe direction of arrow .0, same figure. Fig. 4 is, on an enlarged scale,a detached View of the operating-lever of the reverse-gear mechanismshown at the right in Fig. 1 and showing the reverse-gears in section.Fig. 5 isan end view of the parts shown in Fig. 4 looking in thedirection of arrow (1, same figure, and showing the gears in full linesand the sliding key in section. Fig. 6 corresponds to Fig. 4, but showsthe key and operating-lever in their opposite positions and also shows amodified construction of the locking-lever; and Fig. 7 corresponds tothe lower part of Fig. 1, but shows a gear on the take-up-roll shaftmeshing with a worm on the take-up-driving shaft.

In the accompanying drawings, 1 is a portion of the loom side or frame,2 the stands secured upon the upper part thereof and supporting theseveral parts of the head-motion, and 3 the end of the arch. 4 is thelower cylinder-gear of the well-known Knowles head-motion, (fully shownand described in Reissue "Letters Patent No. 7,784,) fast on the shaft 5and having teeth 4 ona portion only of its periphery. (See Fig. 3.)

On the inner end of the cylindergear shaft 5 is fast a bevel-gear 6,which meshes with and is driven by a bevel-gear 7, fast on the uprightshaft 8. The upright shaft 8 has at its lower end a clutch mechanism ofordinary and well known construction and forming a part of which is abevel-gear 9, which meshes with and is driven by a bevel-gear 10, faston a driven shaft 11, in the usual and well-known way. (See Fig. 2.)

I will now describe the reverse-gear mechanism, which is of the sameconstruction and operation as the reversegear mechanism shown anddescribed in Letters Patent No. 398,328, above referred to.

Loose on the end of the cylinder-gear shaft 5 is a gear 12, which mesheswith a gear 13 of the same size loose on the stud 14, fast in the frame2. Secured to the gear 13, in this instance integral therewith, is asmaller gear 15 in line with a fourth gear 16 of the same size as thegear 15 and loose on the shaft 5 and adjoining the first-mentioned gear12. Gears 15 and 16 are smaller than gears 12 and 13, so that when thegears 12 and 13 are in mesh the teeth of the gears 15 and 16 will cleareach other. (See Figs. 4 and 6.) Gears 12 and 16 are retained on the endof the shaft 5 by a collar 17 and are slotted internally to receive theprojecting end 18 on the key 18, which is adapted to slide freely in aslot or recess 5 in the outer end of the shaft 5 (see Fig. 6) and isprovided with an engaging end or knob 18" and also an annular groove 18for the purpose to be hereinafter described. The two gears 15 and 16 inthis instance mesh ICO ICS

with the gear 19, fast on the endv of the shaft 20, on which is fast theharness-pattern-chain cylinder 21 and the box-pattern-chain cylinder 22.

When the loom is running normally, the key 18 is in its inner positionto attach the gear 16 to the shaft 5,(see Fig. 4,) and the revolution ofthe shaft 5 through gear 16 rotates the gear 19 and the shaft 20 and thepattern-chain cylinders 21 and 22 thereon in a forward direction, thegears 15, 13, and 12 running loose. When the key 18 is in its outerposition, (see Fig. 6,) the gear 12 is attached to the shaft 5 and turnsthe gear 13 and the gear 15, which in turn turns the gear 19 and shaft20 and cylinders 21 and 22 in a reverse or backward direction, the gear16 running loose, all in the usual and well-known way.

I will now describe my improvements combined with the reverse-gearmechanism above described.

The key 18 has an annular groove 18" at its outer end, as above stated,to receive an open-end collar 23, having studs 23 projecting fromopposite sides thereof to enter the open-end slots 24 in the upperforked end 24 on the upper endof the centrally-pivoted lever 24, havin ahub 24 loosely mounted on a stud 25, ast in the end of astand 26, boltedto the frame 2. The lower end of the lever 24 has a stud 27 thereon toreceive the hub 28 (see Fig.5) on one end of a connector 28. The otherend of the connector 28 has a stud 28 thereon adjustably secured in theupper slotted end of one arm of an angle-lever 29, pivotally mounted ona stud 30 on the loom-frame. The other arm of the angle-lever 29 isconnected by a link 31 with one end of a lever 32, having a hub 32pivotally mounted on a stud 33 on the loom-frame. (See Fig. 2.)

The lever 32 has a forked arm 32", having 4 inwardly-extending pinsthereon which eX- tend into an annular groove 34 in the hub of thebevel-gear 34. The bevel-gear 34 is fast on the upper end of sleeve 35,splined on the upright shaft 8 to revolve therewith and to movelongitudinally thereon. On the lower end of the sleeve 35 is fast asecond bevel-gear 36 of the same size as the bevel-gear 34.

A stud 37 is fast at its inner end to the loom-frame and extends outtherefrom. (See Fig. 2.) The outer end of the stud 37 is turned down toreceive the hub 38 of a double bevel-gear 38, which is adapted to meshwith the upper bevel-gear 34, as shown, when the loom is runningnormally or with the lower bevelgear 36 when the sleeve 35 is raised andthe parts are reversing or running backward. The double bevel-gear 38 isalso in mesh with a bevel-gear 39, the hub 39 of which is fast on theshaft 40, leading to the take-up mechanism. One end of the shaft 40 hasa bearing in the stud 37. (See Fig. 2.)

The other end of the shaft 40 has a bearing in a box 41, secured to theloom-frame, and the extreme end of the shaft is provided with ahand-wheel 40. On the shaft 40 is fast a worm 42, which meshes with anddrives a gear 43, fast on the shaft 44 of the take-up roll in the usualway.

In connection with the lever 24, attached to the sliding key 18, Ipreferably use a locking-lever 41, pivotally mounted at one end on astud 42 on the stand 26 and havingv a projection 41 on its upper edge,preferably of wedge shape and preferably made integral with the lever41, as shown in Fig. 3, which is adapted to be engaged by a projection24 on the lever 24, said projection being preferably'of wedge shape. Theprojection 41 on the lever 41 is held in yielding engagement with theprojection 24 on the lever 24 on one side or the other side thereof toyieldingly lock the lever 24 in its opposite positions, in this instanceby a spiral expansion-spring 42, having its ends seated in bosses 43 onthe stand 26 and the lever 41.

From the above description, in connection with the drawings, theoperation of my improvements will be readily understood by those skilledin the art.

When the sliding key 18 is drawn out to reverse the direction ofmovement of the pattern-chain cylinders 21 and 22 through the reversesystem of gears 12, 13, 15, and 16 in the ordinary way, the lever 24will be moved out at its upper end and through connector 28,angle-lever-29, link 31, and lever 32 the sleeve 35 will be raised, asindicated by, broken lines in Fig. 1, to disengage the bevelgear 34 fromthe bevel-gear 38 and bring the bevel-gear 36 into mesh with thebevel-gear 38 to turn said gear in the reverse direction, and throughsaid gear 38 the gear 39 and the shaft 40 to the take-up mechanism toreverse or turn backward the take-up mechanism, as will be readilyunderstood by those skilled in the art. When the sliding key 18 is inits inward position in the normal operation of the loom, the lever 32acts to lock and hold it in its inward position to prevent anyaccidental movement thereof. When the sliding key 18 is inits outwardposition, the lever 41 acts to lock and hold it, through the lever 24,in said position and prevent any accidental movement thereof. At thesame time the lever 24 acts to support the sliding key 18 andhold it inits proper position.

In Fig. 5 is shown a modified construction of the locking-lever 41. Insaid figure instead of having the locking projection 41' made integralwith the lever 41 said projection 41*" is made separate therefrom on acollar 41 adjustably secured on the lever 41 by a screw 41 or otherwise.

It will be understood that the details of construction of myimprovements may be varied, if desired, and they may be adapted to beapplied to any ordinary construction of head-motion and combined withthe reversegear mechanism thereof.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-
